The files in the RECOVER\ENC folder are not corrupted, they are encrypted (hence the name of that directory).
The decryption process is done by the program HG800.EXE in the TOOLS folder of the boot disk (RECOVER\BOOTDISK\SUPPORT.IMG or RECOVER\BOOTDISK.F32\SUPPORT.IMG for FAT32 support). It takes the encrypted directory as the first argument, and the destination drive as the second argument (for example, the command could be "A:\tools\hg800 D:\recover\enc C:").
Regardless of the arguments, that executable stops if it is not run on a real OmniBook 800. Without disassembling or working around this executable, those files are unlikely to be able to be decrypted.
The same goes for my OmniBook 2000 recovery CD, where I have been trying to study how the recovery process works, except the decryption executable is called CD2000.EXE.

Content not corrupted, encrypted, creating the bootdisk and restarting the bootdisk erases al partitions and create new ones and later copy and decrypt all cd contents to HD to start installation.
Needs additional OEM key

Apologies, I previously agreed that this looked corrupted before I tested it -- now tested and looks fine :)

This disk is corrupt. Could you please reupload it?
